The main object of this invention is to studs rotatablysupport arms 26 and :26, provide an attractive toy which operates as which are provided with fan blades 27 and a wind vane for indicating the direction of 27 which are bent to the proper'angle torothe wind. The device uses a plurality ofprotate the arms when the wind travels toward 6*! pcllers which rotate in opposite directions the device. i I i l and the air wash created by these propellers The post 21 has mounted on its side a rudis used by a third propeller which is rotatable der 29 which has a pair of arms 30 which in another plane and is rotated thereby. latter are directly conn'ectedto the post.
